Cabling Arrangement

The cable summary for the PT-650M makes it look much more complicated that it really is. This is because each cable is different from every other. Native cables include the Main, ATX 4+4, and a single PCI-E connector. Everything else is modular. This includes one PCI-E connector, nine SATA connectors over two cables, and four Molex plus a FDD connector over two more cables. Those with multiple hard drives will love the short SATA cable with connectors stacked two inches apart as it really helps keep the cable clutter down on the back side of the drives.

Rail distribution for the PT-650M is relatively simplistic for a quad rail power supply and is noted on the I/O specification label of the power supply. 12V1 powers the Main and all of the peripheral connections while 12V2 handles the ATX 4+4 connector for the motherboard. This leaves 12V3 and 12V4 to each power one of the PCI-E cables.

A Look Inside

Opening things up, we find a minimalistic PCB with a few small heatsinks as is often the case with lower wattage units. They don't require nearly as much passive or active cooling as some of the higher wattage units do.

A single Nippon Chemi-Con capacitor can be found on the primary side of the PT-650M power supply.

More Nippon Chemi-Con capacitors are found on the secondary side as well.
